(01-29-2014, 10:48 AM)Simpler=Better Find someone with a high speed camera, drop the tranny, and record the flywheel flopping around in there. The heavy point will be obvious. Grind as necessary, or re-clock.
Are you reusing the flywheel bolts?
Rollguy over on PP and you have just about the same idea, and im going to steal it and try it.
im not even going to bother with the camera, im just going to pull everything apart, match balance the stock mercedes flywheel and the aluminum flywheel, then look at it in different positions on the engine.
Once I have the two flywheels matched, there are only 12 possible positions for it to be clocked, and one of them is correct. Even if I have to pull the gearbox and test each position individually for vibration with a driving test, it strikes me as less work than ripping the whole motor apart.
At least its a place to start. If I can't nail it down that way, I can always go further on the enigne later
I am reusing the flywheel bolts no more than twice, going through my large collection of them, none of them are loose or stretched out of spec yet.
However, Im thinking of just getting 12 grade 8 bolts that match the threads so I don't have to worry about it. the stock MB bolts are pricey
